Effect of Nanofiller Shape on Effective Thermal Conductivity of Fluoropolymer Composites Report Title Filler particle size and shape influence interconnectivity within a polymer matrix and play a significant role in controlling the effective thermal conductivity of a composite. This study examines the effect of nanofiller particle shape in a polytetrafluorethylene (PTFE) matrix on thermal energ...

Dynamic mechanical analysis was used to study the viscoelastic behavior of nanocomposites consisting thermoplastic corn starch plasticized with glycerol and/or urea and addition 2 or 5 wt. % montmorillonite-type nanofiller. Motional heterogeneity studied materials inferred from temperature dependences damping factor. Relaxation processes in composites only one plasticizer proceeded a similar ma...

Small amounts of inorganic nanofiller material may boost performance for use in next-generation high-energy-density dielectrics.

Properties of cycloolefin copolymer (COC)– polyhedral oligomeric silsesquioxanes (POSS) nanocomposites, prepared by melt compounding, have been investigated. Composites retained the optical transparency of the matrix up to a nanofiller content of 5 wt %. whereas for higher percentages the formation of a crystalline phase, due to the presence of agglomerated nanoparticles, was revealed by X-Ray ...

Polyurethane/graphene nanocomposites were synthesized using commercial thermoplastic polyurethane (TPU, Apilon 52DE55), and two types of graphene derivatives: graphene nanoplatelets (GNP) and reduced graphene oxide (RGO). Fourier Transformation Infrared Spectroscopy Fourier Transformation Infrared Spectroscopy (FTIR) spectroscopy, TEM, and SEM microscopy and XRD techniques were used to chemical...

The heat sealing behavior of novel polyethylene-based nanocomposite films was investigated, as they relate to flexible packaging of fresh-cut vegetables, processed foods and biomedical devices. Appropriately designed sealant nanocomposites, which include dispersed montmorillonite nanofillers and ethyl vinyl acetate copolymer, produce a hermetic but peelable heat seal across a broad, 30–40◦C, ra...

In this study, the mechanical properties of epoxy nanocomposites with graphene platelets, single-walled carbon nanotubes, and multi-walled carbon nanotube additives were compared at a nanofiller weight fraction of 0.1 +/- 0.002%. The mechanical properties measured were the Young's modulus, ultimate tensile strength, fracture toughness, fracture energy, and the material's resistance to fatigue c...

Shape memory nanocomposites are excellent smart materials which can switch between a variable temporary shape and their original upon exposure to external stimuli such as heat, light, electricity, magnetic fields, moisture, chemicals, pH, etc. Numerous nanofillers have been introduced in polymers carbon nanotubes, graphene, nanodiamonds, nanofibers, Among nanocarbons, graphene has attracted res...
